@MojangSupport Hello, I recently had the urge to play minecraft again. However, it was impossible to log into my account without migrating it to a microsoft account. So I was forced to do this migration but now I no longer have the game. How can i get my account back?

It likely means that you're not logging in with the correct credentials! help.minecraft.net/hc/en-us/… ^TK

It looks like there's actually an issue with Minecraft authentication right now, me and a few people who run a private server have tried everything to eliminate any user error that may have caused it, it looks to be on Mojang/Microsoft's side

Update on this, issue appears to be resolved
